Audit in 60 days — sound familiar?
- ▸ PII stored in plain BSON fields — Customer email, phone, payment-token fields in clear text; Atlas Encryption-at-Rest covers disk but not query-level — auditor wants Field-Level Encryption (CSFLE).
- ▸ SCRAM-SHA-1 still enabled — Legacy SCRAM-SHA-1 is still permitted because old drivers block switching to SCRAM-SHA-256-only; the auditor flagged the weak SHA-1 hashing as a finding.
- ▸ Atlas IP allowlist set to 0.0.0.0/0 — Either "allow all" for dev convenience that never got tightened, or the VPC peering never completed and someone left the back-door open.

Fixed-scope, 2-week delivery
MongoDB Security Audit — CIS Benchmark, PCI-DSS, HIPAA, SOC 2
In short: A MongoDB security audit reviews 12 control areas — Client-Side Field-Level Encryption (CSFLE) / Queryable Encryption, x.509 authentication, SCRAM-SHA-256, Atlas Encryption-at-Rest with customer KMS, network peering instead of 0.0.0.0/0, least-privilege roles, and audit logging — then delivers a written report with severity-ranked findings and PCI-DSS / HIPAA / SOC 2 control mapping.
Production MongoDB security audit covering Queryable Encryption (CSFLE), x.509 auth, field-level encryption, Atlas Encryption at Rest. Written report with severity-ranked findings, compliance-framework control mapping, and a 12-month remediation roadmap. Designed for teams preparing for PCI-DSS v4.0, HIPAA, or SOC 2 Type II audit windows.
JusDB conducts rigorous 12-point zero-trust MongoDB security audits to protect production database estates against ransomware, data exfiltration, and compliance penalties. Certified DBREs enforce SCRAM-SHA-256 authentication, configure TLS 1.3 wire encryption, deploy WiredTiger encryption-at-rest, implement Client-Side Field Level Encryption (CSFLE), and configure immutable audit logging aligned with SOC 2, HIPAA, and PCI-DSS.
What We Audit
12 control areas, fully assessed
Every audit covers these MongoDB-specific controls. Findings are severity-ranked (Critical / High / Medium / Low) with remediation effort estimates and compliance-framework mapping.
Compliance Mapping
Every finding mapped to a framework
The audit report includes a control-mapping matrix so your compliance team can hand it directly to an auditor without re-translating the findings.
| Framework | Scope | Coverage |
|---|---|---|
| PCI-DSS v4.0 | Cardholder data systems | Encryption-at-rest, TLS for transport, audit logging, access control, vulnerability management |
| HIPAA Security Rule | PHI databases | Access control, encryption, audit logs, integrity validation, transmission security |
| SOC 2 Type II | Customer data systems | Security, availability, confidentiality — continuous control testing over 6+ months |
| ISO 27001:2022 | Information security management | Annex A controls 5.x-8.x covering DB access, cryptography, supplier relationships |
| GDPR Article 32 | EU personal data | Pseudonymisation, encryption, confidentiality, integrity, availability, resilience |

How JusDB Security DBRE compares to alternative models.
Standard compliance checklists and generic auditors lack deep MongoDB engine internals, Wire Protocol inspection capabilities, Queryable Encryption expertise, and cryptographic key lifecycle governance. Here is how our certified security specialists compare:
| Evaluation Vector | JusDB DBRE | In-House DBA | Legacy Agency | Developer Generalist |
|---|---|---|---|---|
| SCRAM-SHA-256 & x.509 PKI Mutual Authentication | Enforces strict SCRAM-SHA-256 or dual-layer x.509 client certificate authentication; purges legacy SCRAM-SHA-1 and MONGODB-CR mechanisms across all databases. | Permits legacy SCRAM-SHA-1 passwords with weak iteration counts, leaving user credentials vulnerable to offline dictionary and rainbow table attacks. | Deploys shared static administrative passwords in application config files without rotation schedules or certificate revocation lists. | Leaves authentication disabled (auth=false) during initial staging and forgets to enable security prior to promoting endpoints to production. |
| TLS 1.3 Encryption-in-Transit & Strict Cipher Enforcement | Enforces TLS 1.3 across all cluster nodes and client drivers with strict forward secrecy ciphers (e.g. TLS_AES_256_GCM_SHA384) and certificate expiration alerting. | Enables allowInvalidCertificates or allowInvalidHostnames flags in connection strings to bypass TLS certificate chain validation errors. | Permits deprecated TLS 1.0/1.1 protocols and weak CBC ciphers, failing automated PCI-DSS v4.0 and SOC 2 external compliance scans. | Runs unencrypted plaintext MongoDB wire protocol over port 27017, exposing sensitive JSON payloads to network packet sniffing. |
| WiredTiger Transparent Data Encryption (TDE) & KMIP Key Management | Integrates WiredTiger encryption-at-rest using hardware AES-256-CBC via KMIP or cloud KMS (AWS KMS, GCP Cloud KMS, Azure Key Vault) with automated master key rotation. | Relies solely on cloud hypervisor volume encryption (EBS/GCP disk encryption), leaving local database memory dumps and unattached snapshots unencrypted. | Stores KMIP encryption keys directly on the database host filesystem alongside encrypted data files, invalidating at-rest protection. | Disables native database encryption-at-rest completely, storing sensitive document data files in plaintext on disk. |
| Client-Side Field Level Encryption (CSFLE) & Queryable Encryption (QE) | Architects zero-knowledge cryptography using CSFLE and MongoDB Queryable Encryption (QE) so encrypted fields remain unreadable even to database administrators and cloud hosts. | Attempts custom application-level encryption functions that break query indexing, sort operations, and range filtering. | Recommends against field-level encryption citing query limitations, ignoring modern Queryable Encryption equality and range search capabilities. | Stores plaintext PII, credit card tokens, and healthcare data directly in standard collections, risking catastrophic regulatory data breach penalties. |
| Fine-Grained Role-Based Access Control (RBAC) & Principle of Least Privilege | Audits and prunes over-privileged accounts, replacing root and dbOwner assignments with scoped custom roles containing granular collection-level readWrite privileges. | Assigns broad readWriteAnyDatabase or userAdminAnyDatabase roles to all application service accounts to avoid permission troubleshooting. | Shares a single global database administrator user across developers, contractors, and background jobs with zero individual accountability. | Uses the default root user for all application backend database connections, enabling any compromised service to drop entire databases. |
| Immutable JSON Audit Log Streaming to SIEM (SOC 2 / HIPAA / PCI-DSS) | Configures granular audit filters for authentication, DDL changes, and authorization failures, streaming structured JSON audit logs in real-time to Splunk, Datadog, or S3. | Enables indiscriminate audit logging that captures all read queries, saturating disk IOPS and causing database latency spikes before being manually disabled. | Leaves audit logging disabled, producing zero forensic evidence or compliance audit trails required for SOC 2 Type II or HIPAA certification. | Relies on standard application log outputs without capturing database-level user authentication events or schema mutations. |
MongoDB Security Failure Modes
Critical Security Vulnerabilities We Eliminate
Default configurations and unhardened MongoDB environments present critical vulnerabilities that expose organizations to automated ransomware, unauthorized collection drops, and catastrophic disk starvation. Our DBREs resolve these high-risk failure modes:
Default Unauthenticated Bind IP Exposing Database to Public Internet
Deploying mongod with bindIp: 0.0.0.0 or binding without authorization (auth: false) exposes port 27017 directly to the public internet. Automated ransomware bots detect open ports within minutes, dump unencrypted collections, drop databases, and demand extortion ransoms.
JusDB enforces bindIp to private VPC subnets, mandates authorization: enabled, isolates instances behind cloud security groups, and sets up automated external exposure port scanners.
Over-Privileged Application Credentials Allowing Collection Dropping
Granting broad administrative roles such as root or dbOwner to backend microservices violates the principle of least privilege. SQL injection, NoSQL injection, or application credential leaks grant adversaries full permissions to drop transactional collections or exfiltrate customer databases.
JusDB designs granular custom RBAC roles restricting application microservices to explicit collection-level find, insert, and update actions while revoking dropCollection, dropDatabase, and eval permissions.
Unfiltered Audit Logging Triggering Severe Disk IOPS Starvation
Enabling blanket database audit logging without event filters writes every internal read, aggregation, and connection event to the audit log. High-concurrency query traffic saturates disk IOPS, creating intense storage contention with WiredTiger checkpoints and stalling transactions.
JusDB configures targeted JSON audit filters capturing strictly authentication failures, user management, and schema DDL mutations, streaming events to external syslog or SIEM daemons without local disk write bottlenecks.
Our MongoDB security engineers execute read-only administrative inspection commands to verify active authentication mechanisms, TLS wire configurations, and administrative role assignments:
Inspects active connection authentication credentials, transport encryption modes, and permitted authentication mechanisms.
# 1. Inspect authenticated user status and connection security
mongosh "mongodb://localhost:27017/admin" --eval "db.runCommand({connectionStatus: 1})"
# 2. Check active TLS mode and enabled authentication mechanisms
mongosh "mongodb://localhost:27017/admin" --eval "db.adminCommand({getParameter: 1, tlsMode: 1, authenticationMechanisms: 1})"Queries the admin user catalog to locate accounts provisioned with administrative superuser roles (root, dbOwner, userAdminAnyDatabase).
# 1. Audit administrative and superuser role assignments across all databases
mongosh "mongodb://localhost:27017/admin" --eval "db.getUsers({filter: {roles: {\$elemMatch: {role: {\$in: ['root', 'dbOwner', 'userAdminAnyDatabase']}}}}})"FAQ
